<p>The module has a door frame constituted of parallel and symmetrical posts (4). The posts are fixed to a crossbeam such that the posts define spaces for receiving a transom and a door with the crossbeam, respectively. Each post has a frame (40) formed of a wing (41) and a body part (42), and a counter-frame (43) formed of a wing (44) and a body part (45), where the positioning of the counter-frame opposite to the frame is adjustable to vary a mutual gap between the wings. An incompressible wedge (7) is extended between the frame and the counter-frame.</p> |
